Publishing (Controlling When & How Items are Displayed)

Publishing Content
Moving content between the three basic workflow states (private, pending review, and published) is very easy.
Scheduling Content
By default, the publication date of an item is set to the date and time at which the item’s state is first changed to "published". Some items on your site, such as news items and events, will contain time-sensitive information. You can set a "publishing date" and an "expiration date" to control visibility. Although you can set an expiration date for any item, content that you want to remain on your site indefinitely should not be assigned an expiration date.
